IMPROVEENT IN LARD-PRESSES.

Specification forming part of Letters Patent No. 132,486, dated October 22, 1872.

To all whom it may concern:

Beit known that we, WASHINGTON.F. PA- enrr and CHRIsTIAN F. ROIIRER, of Fremont, in the county of Clark and State of Ohio, have invented a new and Improved Press for Extractin g Liquids from Solids, of which the following is a specification:

This invention relates to that class of presses which are provided with foraminous pressboxes, and followers for extracting liquids from various solid substances, such as lard, fruits, cheese, &c. Theinvention consists principally in the provision of a vibrating or movable post or block, which is applied to the follower of the press for transmitting to the same the pressure exerted by a lever which has its fulcrum-point in a stationary ratchetplate secured to a vertical standard.

In. the drawing, Figure l is a side elevation with parts broken out, and Fig. 2 is a top view. Fig. 3 is a detail view of the lever.

A represents the bed-frame or supporting stand of the press. B is a vertical standard attached to the stand by a transverse key and secured in position by a lateral brace, a. O is the press box or hopper formed of foraminous metal or wood, and which may be of any desirable size and shape. D is a detachable or separate hopper-bottom provided with vertical flanges b to form a trough or channel surrounding the press-box for conducting the expressed liquid to a discharge-spout, c. E is a device for fastening the hopper and its bottom to the bed-frame, consisting of a metal rod having hooks at both ends for insertion into the staples or eyes d attached to the pressbox and stand. F is a horizontal-enlargement of the upper end of the standard B, in the under side of which is formeda notch or groove for the reception of a locking wedge or key, G, which presses against the upper edge of thepress-box for securing the same in position. H is the follower of the press carrying a vertical vibrating post, I, the lower end of which is provided with a horizontal cylindrical tenon, J. K K are centrally-divided boxes or battens which are secured to the follower and provided with cylindrical sockets or channels for receiving the cylindrical tenon of the post I. L is a metallic plate or check-plate, hinged at its lower end to the follower or battens, and provided at its upper end with an elongated slot, M, through which passes a headed bolt or button, N, secured to the vibrating post. 0 is a plate with a notched or ratchet surface secured to the upper end and vertical edge of the standard B. P is the lever for operating the follower of the press, the inner end of which is armed with a metal plate having a curved projection, g, engaging with the ratchet-plate O, which thus forms the fulcrum-point of the lever. The lever is detachably connected with the vibrating post by inserting the upper convex end of the latter into a concave channel in the under side of the lever. The lateral movement of the same, when in operation, is further prevented by a pin, Q, projecting from the upper end of the vibrating post which enters a suitable opening in the lever.

The advantages derived'by the use of the vibrating post are as follows, viz.: By reason of the peculiar method of attachment it will, during the operation of pressing, have a tendency to be drawn toward the fulcrum-point of the lever, thus bringingthe fulcrum and point at which the weight or pressure is applied, in close proximity, and affording a greater leverage with a small exertion of power. The degree of vibration of the post is determined by the depth of the notches in the fulcrum-plate, and the pitch or distance from the points of the lever, and the movement of said' post is regulated through the medium of the slot in the check-plate. Said plate will also serve as a brace for preventing the vibration of the post in more than one direction, as the limit of its movement is a vertical position, and toward the fulcrum-point of the lever.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-- The vibrating post I,check or regulating plate L, and fulcrum or ratchet-plate 0, when combined with lever P and follower H, and relatively arranged in the manner specified.
